"Gong Jiang, that is the combined machine tool for primer processing. Those machine tools are also the most precise machine tools. Those machine tools are the machine tools from Hans that were purchased in SL at that time and were assembled by their engineers.

Now is the treasure in their factory! With it, their production efficiency will be doubled."

Hu Dahai pointed to several machine tools that were different from other machine tools and introduced them.

It turns out that assembling a finished bullet is divided into two parts, mainly the cartridge case, that is, the processing of the primer and the assembly of the finished bullet (the assembly of the cartridge case and the warhead).

The primer of each bullet is the most critical part of that bullet. If the primer is damaged during production and transportation, it is very likely to have unimaginable consequences at any time.

Shortly after the founding of the People's Republic of China, other countries began to use modular machine tools with higher precision in the processing of primers to reduce manual operations as much as possible to improve production efficiency and safety.

After installing the primer, the machine tool also applies sealant between the primer and the cartridge case to prevent the primer from getting wet and causing the bullet to fail.

Seeing some female workers checking the bullet casings that had been installed with ground fire, Jiang Yan asked curiously.

"That needs to be checked very much!"

"That's wrong! Need to check and select those that are inappropriate before entering the East First Stage."

After Hu Dahai said that, he explained: "Female workers are more attentive than male workers, so they check whether the ground fire has been installed properly. Basically, the ones in use are not female workers."

After listening to Hu Dahai's explanation, the inspection nodded and did not shut up. Xu Damao, who was next to Bu Nao, looked at the female workers working with interest, and angrily Jiang Yan gave him a kick.

"Then what kind of paint was applied on it?"

Jiang Yan curiously pointed at the workers painting the connection between the bullet casing and the bullet and asked curiously.

"Oh, did they apply insulating paint?"

Through Hu Dahai's explanation and inspection, we found that before the warhead is officially loaded into the cartridge case, the machine tool will apply a layer of sealing paint on the mouth of the cartridge case. Since metal processing will produce certain errors after all, it is difficult to ensure that the gap between each cartridge case and the warhead is

They all fit together so tightly, so applying sealant paint can completely isolate the outside air and prevent the gunpowder outside the cartridge case from getting damp and affecting the elasticity of the bullet.

After that, the bullet enters the assembly line. A professional bomb-forming and assembly machine tool first pours the weighed propellant into the bullet case, and then squeezes the warhead into it. After weighing inspection and appearance inspection, a qualified bullet is born.

"It turns out that there are so many processes involved in producing bullets! He thought it was too simple before." Jiang Yan sighed while holding a bullet that had been made.

"No! Boss, will he have an eye-opening experience tomorrow? It's so shocking," Xu Damao said next to him.

“All the machines in Bu Nao are manufactured abroad, and I don’t know when we will be able to use our own machines to produce bullets.”

Hu Dahai also said something with emotion.

After hearing what Hu Dahai said, Jiang Yan looked at the workers who were leaving and said, "There will be a day."

Hu Dahai heard Jiang Yan's words and muttered to himself: "No! There will be a day."

When people are busy, it seems that time flies very fast. After visiting the bullet production, two months have passed unknowingly. At this time, the time has come to July, and the weather is gradually getting hotter.

stand up.

The weather in Buona Ice City in July is much better than that in Shijiu City. Although it has already entered summer, the weather there is the same as the weather in Kokuma in April and May, very refreshing.

During those two months, Jiang Yan and his workers began to repair other machines. With the help of computers in his own space, Jiang Yan restored several machines, and the drawings of those machines were quickly studied by dedicated personnel.

Experimental production began at Fengtian No. 1 Machinery Factory. As a reverse imitation engineer, Jiang Yan was called over to guide several times. Under Jiang Yan's guidance, the first batch of machine tools was successfully produced by Fengtian No. 1 Machinery Factory.

, those machine tools were soon shipped across the country, greatly alleviating the shortage of machines outside the factory.

I would like to ask Jiang Yan whether there is any personal information mixed in, so the answer must be no. How can he be able to claim his identity as a time traveler if there is no personal information mixed in?

Among the drawings for the imitation machine tools, Jiang Yan also sent them the drawings of the CA6140 lathe developed by Fengtian No. 1 Machine Tool Factory in 1974.

CA6140 is a horizontal lathe that is improved on the basis of the original C620 ordinary machine tool. In the machine tool naming, C stands for lathe and A is the structural characteristic code to distinguish C6140. 6 stands for horizontal type, 1 stands for basic type, and 40 stands for

The maximum rotation diameter is 400MM, which is one of the equipment required by mechanical equipment manufacturing enterprises.

The CA6140 lathe has a complex structure and a wide range of capabilities. It is suitable for processing various rotating parts. Its tool holder can hold four different turning tools at the same time. Four different turning tools can be used alternately by rotating the tool holder under different working conditions.

The wrong tool is used to process the workpiece.

That machine tool was widely used in later generations and has a wide range of uses. It can be used for rough machining and finishing of mechanical parts. It has a reliable structure, easy operation, economical and practical. The control system has complete functions and high reliability. This machine tool can satisfy many needs.

The needs of industries, such as: automobiles, tractors, military industry, machinery and other industries. The machine tool is especially suitable for efficient processing of external cylindrical surfaces, tapers, threads, drilling, reaming and curved rotary parts of shafts and disk parts.

High-volume turning operations.

This was the first machine tool that Jiang Yan came into contact with in later generations. He had dismantled that machine tool countless times when he was studying in school. Jiang Yan was so familiar with the structure inside that he could draw its structure diagram with his eyes closed.

.

The most important thing is whether according to the current production level of the country, Fengtian No. 1 Machine Tool Factory is fully capable of producing that kind of machine tool. Originally, that kind of machine tool is the product it is responsible for developing. Jiang Yan put that kind of machine tool into production.

If the machine tool is given to them, it will be returned to its original owner in disguise.

During those two months, every Sunday, Jiang Yan went to Hao Pingchuan's house, and Hao Pingchuan came to the factory to pick up Jiang Yan. In order to facilitate Hao Pingchuan's entry and exit, Jiang Yan specially arranged a check-in for him.

Special pass.

I have to say that the generosity of Northeastern people is vividly displayed in Hao Pingchuan's daughter-in-law Yang Xiaomei. Every time he goes to his home, he will prepare a lot of Northeastern specialties to entertain Jiang Yan and the others.

Everyone has a limited amount of meat tickets every month. Even if it were Hao Pingchuan, the police chief probably didn't have much. Jiang Yan was also curious about why Hao Pingchuan's family had so much meat. Through Yang Xiaomei's explanation, Jiang Yan only understood that Yang

Xiaomei's father was an old hunter, and his marksmanship was really superb. At that time, there were a lot of prey in the forests of Northeast China. Every time he went into the mountains, he would come back with a full load. Most of the prey was sold to the supply and marketing cooperative, and the rest became his own.

The food in the family's mouth, and since Yang Xiaomei was the only girl in their family, she was naturally favored and given more things.

Northeastern people like to drink. How come they can't get enough of wine at every gathering? Jiang Yan found that Yang Xiaomei's drinking capacity was not much worse than the two of them. The good-for-nothing Bu Nao was still a good-for-nothing, and Xu Damao still drank just a few ounces.

According to Yang Xiaomei's record, Xu Damao's drinking capacity would not be enough for them to survive at the children's table.
